Vegans (say "VEE-guns" or "VAY-guns") are
total vegetarians. They eat only plant foods. They don't eat food that comes
from animals in any way, including milk products, eggs, honey, and gelatin
(which comes from bones and other animal tissue).

Many people are semi-vegetarian—most of the diet is vegetarian, but sometimes they may eat meat, poultry, seafood, fish, and/or eggs.
